Abstract
The utility model relates to a two ditch bearings of extension, including the pivot, the axle sleeve in the pivot outside is established to the cover, all is equipped with the raceway in the both sides of axle sleeve, is equipped with the steel ball in the raceway, is equipped with the holder in the outside of steel ball, and the both ends department between pivot and the axle sleeve is equipped with the shield, and this shield is circularly, and is equipped with the connecting portion that extend outwards in the edge of shield, and the free end of connecting portion has the arc flange, is equipped with the arc flange of being convenient for on the medial surface of axle sleeve and inserts the just spread groove of block. Carrying out shield when installation, directly establishing the outside and axial compression shield in the pivot with the shield cover, back in the spread groove, spread groove and arc flange looks block are squeezeed in to arc flange on the shield connecting portion to prevent that the shield from droing from between pivot and the axle sleeve, the medial surface at axle sleeve both ends be the inclined plane, is convenient for impress the shield simple to operate of this bearing, and when rotating relatively noiseless of pivot and axle sleeve, convenient to use between shield follow pivot and the axle sleeve.
Description
Technical field
The utility model relates to a kind of bearing, the two ditch bearing of especially a kind of lengthening.
Background technique
Bearing uses widely at mechanical field, mainly play reduction of speed, increase the effect of moment of rotation, in order to strengthen the stationarity that bearing rotates, occurred two ditch bearing, two ditch bearing is the same with other bearing, also needs to be undertaken dust-proof by installing dust cover, but present two ditch bearings are substantially all stuck between axle sleeve and rotating shaft when settling dust cover, and when rotating, dust cover easily produces noise, there is certain defect.
Model utility content
The purpose of this utility model is the defect in order to solve in prior art existing for two ditch bearing, the two ditch bearing of the lengthening providing a kind of dust cover easy for installation.
To achieve these goals, the technical solution adopted in the utility model is:
The two ditch bearing of a kind of lengthening, comprise rotating shaft, be set in the axle sleeve outside rotating shaft, be equipped with raceway in the both sides of axle sleeve, in raceway, be provided with steel ball, retainer is provided with in the outside of steel ball, two end part place between described rotating shaft and axle sleeve is provided with dust cover, and this dust cover is rounded, and is provided with the joint extended outwardly in the edge of dust cover, the free end of joint is with curved flanges, and the inner side surface of described axle sleeve is provided with the connecting groove being convenient to the insertion of described curved flanges and engaging.
Above-mentioned one lengthens two ditch bearing, and the inner side surface at described axle sleeve two ends is inclined-plane.
Above-mentioned one lengthens two ditch bearing, and the material of described dust cover is nylon.
Above-mentioned one lengthens two ditch bearing, and the inside of described rotating shaft is provided with multiple stiffening rib.
Above-mentioned one lengthens two ditch bearing, and the outside of described axle sleeve is with mounting groove.
The beneficial effects of the utility model are: the edge of the dust cover of the two ditch bearing of this lengthening is provided with the joint extended outwardly, the free end of joint is with curved flanges, the inner side surface of axle sleeve is provided with the connecting groove being convenient to curved flanges insertion and engaging, when carrying out dust cover and installing, directly dust cover is set in the outside of rotating shaft and axial compression dust cover, curved flanges on dust cover joint is squeezed into after in connecting groove, connecting groove and curved flanges fasten, thus prevent dust cover from coming off between rotating shaft and axle sleeve, the inner side surface at axle sleeve two ends is inclined-plane, be convenient to dust cover be pressed between rotating shaft and axle sleeve, the dust cover of this bearing is easy for installation, and rotating shaft and axle sleeve noiseless when relatively rotating, easy to use.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the A district enlarged view in Fig. 1.
Embodiment
Further understand for making to have structure characteristic of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1 and Figure 2, the two ditch bearing of a kind of lengthening, comprise rotating shaft 1, be set in the axle sleeve 2 outside rotating shaft 1, raceway is equipped with in the both sides of axle sleeve 2, steel ball 3 is provided with in raceway, retainer 4 is provided with in the outside of steel ball 3, two end part place between rotating shaft 1 and axle sleeve 2 is provided with dust cover 5, this dust cover 5 is rounded, and the joint 6 extended outwardly is provided with in the edge of dust cover 5, the free end of joint 6 is with curved flanges 7, and the inner side surface of axle sleeve 2 is provided with to be convenient to curved flanges 7 and to insert and the connecting groove 8 engaged.
Further, the inner side surface at axle sleeve 2 two ends is inclined-plane, and the material of dust cover 5 is nylon, and the inside of rotating shaft 1 is provided with multiple stiffening rib 9, and the outside of axle sleeve 2 is with mounting groove 10.
The edge of the dust cover 5 of the two ditch bearing of this lengthening is provided with the joint 6 extended outwardly, the free end of joint 6 is with curved flanges 7, the inner side surface of axle sleeve 2 is provided with to be convenient to curved flanges 7 and to insert and the connecting groove 8 engaged, when carrying out dust cover 5 and installing, directly dust cover 5 is set in the outside of rotating shaft 1 and axial compression dust cover 5, curved flanges 7 on dust cover joint is squeezed into after in connecting groove 8, connecting groove 8 and curved flanges 7 fasten, thus prevent dust cover 5 from coming off between rotating shaft 1 and axle sleeve 2, the inner side surface at axle sleeve 2 two ends is inclined-plane, be convenient to dust cover 5 be pressed between rotating shaft 1 and axle sleeve 2, the dust cover 5 of this bearing is easy for installation, and rotating shaft 1 and axle sleeve 2 noiseless when relatively rotating, easy to use.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
